Public Key Cryptography
An introduction to a powerful cryptographic system for use on microcomputers.

Cryptography, the art of concealing the meaning of messages, has been practiced for at least 3000 years. In the past few centuries, it has become an indispensable tool in the military affairs, diplomacy, and commerce of most major nations. During that time there have been many innovations, and cryptography has changed and grown to accommodate the increasingly complex needs of its users. Present techniques are very sophisticated and provide excellent message protection. Current developments in computer technology and information theory, however, are on the verge of revolutionizing cryptography. New kinds of cryptographic systems are emerging that have incredible properties, which appear to eliminate completely some problems that have plagued cryptography users for centuries. One of these new systems is public key cryptography.

"Radio Shack's TRS-80 Computer Is the Smartest Way to Write"
Our word processing system changed Isaac Asimov's mind about writing-and he's a renowned science and science fiction author! But you don't have to be an author to use a TRS-80. If you prepare memos, letters and reports-do what Isaac did. It will change your mind, too.
"I may never use a typewriter again!" Isaac likes the time he saves using SuperSCRIPSIT™ (26-1590, $199), our newest word processing program. "For example, I can assign frequently-used words and phrases to a user-defined key. So whenever I press that

MULTIPROCESSOR WITH 64 BIT PROCESSING POWER.
Dazzled by 16-bit and 32-bit machines? When it comes to multiuser applications you've got to talk about TOTAL processing power. Not just the number of bits on a single processor.
In our new Betasystem II multiprocessor, we put eight SLAVENETâ„¢ processor boards together to give you 64-bit processing throughput. That's because the SLAVENET boards work in parallel to gobble up 64 bits of data each cycle.

Compuserve Trademarked the Word "Email"

Microcomputing, British Style
The Fifth Personal Computer World Show
by Gregg Williams, Senior Editor
Quick: what's the most microcomputer-hungry country in the world? The United States, of course, right? We've got Silicon Valley and Route 128 (recently dubbed Technology Highway) near Boston. We've got BYTE, Apple, Atari, and IBM. True enough, but Britain has the people and it has a lot more than we do.
There's ample evidence that, compared to the U.S., proportionally more of Britain's population is interested in microcomputers. The Fifth Personal Computer World Show, a business and hobby microcomputer show hosted by one of Britain's leading computer magazines, Personal Computer World, is a case in point. From September 9 to 12, 1982, 47,461 people attended the showâ€”12,000 more than visited this year's West Coast Computer Faire, which also lasted four days and wasâ€”until nowâ€”the world's largest microcomputer show.

Byte Reviews the Compaq - First PC Clone
A portable and affordable alternative to the IBM Personal Computer.
Mark Dahmke Consulting Editor
What emulates an IBM Personal Computer, can easily be carried from place to place, and costs a lot less than the competition? The Compaq computer, and because it can run any major business and professional software written for the IBM PC, it looks like a sure winner. I visited the Compaq Computer Corporation's headquarters in Houston recently to try out a prototype of its brainchild.
